This paper proposes a new query expansion method which combines user modeling research and the research of query expansion based on Ontology,realizing the personalized semantic query expansion. And it divides the process of personalized semantic query expansion into two stage ——the mapping from keywords to the concepts included in the user modeling and the semantic extension at the level of Ontology, and the algorithm of each stage is gaven in this papar. The experiment indicates that this method can enhance the accuracy ratio and the recall of the information retrieval, and meet personalized needs in the certain extent.
